In
the eighteenth and nineteenth century, the vast wealth and land holding of the
Knox family can not be underestimated. The family had estates all over Mayo and
as different branches of the family grew so did the families collection of
houses. Names of family homes in Mayo, some of which still exist, include Rappa  Castle , Mount  Falcon , Belleek  Castle ,
Castle Lacken, Netley  Park Dublin  and the UK  together with Woodstock Surrey  in December 1835. She was the elder daughter
of Lawrence, 2nd Earl of Ross and sister of William Parsons, the 3rd Earl of
Rosse of Birr Castle.  Arthur was the eldest son of  John Knox and
after his  death, his estates in Mayo were sold in the Encumbered Estates
Court in 1853. It appears that the estate was possibly entailed to the eldest
son as Arthur's son, Lawrence (who was a minor at the time) was also mentioned
as being an owner in press advertisements when the estate was sold. The first
sale of land owned by Arthur Knox extended to over 16,000 acres with the second
sale amounting to over 25,000 acres. Arthur Knox appears to be living in Sussex

Ernest
made a number of changes to the house, none of which improved its appearance
internally or externally. He divided up the entrance hall to create unneeded
additional rooms and as per the attitude of the previous generations never
completed the endeavor. He decided to close up the original main entrance to
Castlereagh and re-orientate the house. The new entrance that was created was
through a small glass door which seemed very odd in a building of such a vast
size. Lots of projects were begun in the house but were never completed which
were often lamented by later generations.  Pictures were removed from the
walls to be re-hung but were still on the floor over fifty years later.
Apparently in later years as areas of the house deteriorated the inhabitants
moved to other parts of the house that were unaffected. This resulted in there
being four incarnations of the kitchen as it followed the family around their
decaying home. The house was adapted over the generations in an ad hoc manner,
there were five staircases one of which was said to be the inspiration for the
staircase that exists today in Cillaithe House in nearby Killala also owned by
a Knox relative. In 1812, the north

With
a large rambling country house of its size, there was tales of ghosts
especially a deceased butler who would make his way through the passages of the
house at night dropping crockery. Naturally enough there was also a haunted
room that no one was meant to disturb. The room contained an apparition that
would rearrange the belongings of any guest foolish enough to stay there. It
wasn’t unusual for rooms to be locked and forgotten about in Castlereagh, one
such room was locked after one of the estate's agents drowned who occupied it.
The room remained locked for over sixty years and was only opened to retrieve
the contents after the floor began to collapse in that section of the house. In
fact it appeared to be a tradition, that as the family members died and the
size of the family began to decrease, the bedroom of the deceased was locked
and remained as it was at the time of the person’s death. It was said that
whenever a member of the Knox family who lived in the house was about to die, a
ghostly horse and carriage would descend from the heavens and arrive at the
door of Castlereagh to carry the recently deceased to heaven...... or hell, it
was never determined where its destination was.

It
was Ernest's nephew Lawrence Knox who established the Irish Times in 1859
although it is said that he made no money from it.  He was the son of
Arthur Edward Knox who sold Castlereagh. Lawrence Sussex Crimea  during
the Russian War. He was eventually elected to Parliament as a representative

By
1911, John Valentine Knox is resident in the house with his sister Helen but
they are now joined by their brother Ernest and another sister Gertrude. Ernest
Knox who was born in 1846, retired from his position in the banking profession
in 1910 and returned to his Mayo home. They have four live in servants in the
house.  It is said that John and Ernest’s sister Gertrude always wore a
hat all the time and was never seen without it for the sole reason that she had
no hair. John Valentine died in 1919 followed by Gertrude in 1923. The last
residents of the house was Ernest Knox and his sister Helen. The attitude of
the previous generations to lock up rooms and forget about parts of the house
was still prevalent in Ernest. Once when showing a guest around the house they
enquired what a large heavy timber cupboard situated on the landing contained.
Now one must remember that Ernest had lived in the house since childhood for
over eighty years so his response might surprise some. He replied that he had
never had the sufficient curiosity to open it. One relative whose boxes of
possessions returned to the castle after their death in 1876 remained unopened
by the time it came to clear the castle in 1933. Another box which was
transferred from Woodstock

In
April 1930, Ernest Knox aged 84 was laid to rest in the private cemetery within
the demesne, today this area is marked by a group of trees, and though it
exists on private lands it is said that the grave markers remain. Only Ernest's
elderly sister Helen aged 90 and a few relatives attended his funeral. 
Ernest spent his time at Castlereagh in his notable library or trout fishing on
the nearby river. His herd of deer, which galloped around the demesne, was said
to be second only to the one that the Guinness family kept at Ashford  Castle Ireland  and the UK Birmingham Manchester 
In
December of the same year, tenders were invited for the purchase of the timber
on the lands of the estate which comprised of 2,500 trees made up of Ash, Oak,
Elm, Beech, Sycamore and Larch. The house was bought by Arthur West of Ballina
who intended to demolish it for materials. In 1937 the demolition of
Castlereagh began but resulted in a tragedy. Michael Burke, aged 18, was killed
during the demolition of the house when a wall collapsed on him. Even during
the demolition of the house Castlereagh had one more secret to reveal, as
another staircase was uncovered having being built up decades before. The
destruction of the great house was now complete, it was wiped from the
landscape as if it never existed and today the field where it once stood gives
no hint to what was once there.
